An efficient generic method for calculating the properties of combustion products

A simple method for calculating the properties of combustion products is pr esented. The method is generic: the same equations apply to any fuel for an y fuel-air ratio and temperature. The equations are suitable for both hand calculation and computer applications requiring repetitive property evaluat ions. The present equations offer accuracy comparable with the most elabora te method available but at a significantly reduced computational cost. The theory should find direct use in design-point and off-design performance ca lculations and optimization of internal combustion engines, e.g. gas turbin e plants, calculation of the three-dimensional flowfield within a multistag e turbine, and other applications requiring properties of combustion produc ts.
